gloriouscowAs retrocomputing enthusiasts, its easy for us to lose track of the fact that the average person may only reverse-engineer 1-2 high resolution light pen interface cards in their entire lifetime.
Rue Mohr@gloriouscow oh "high rez" now!
@RueNahcMohr nearly 4k of horizontal resolution!
@gloriouscow is the sweep event that stable???
57khz, ...228MHz? 4.4ns?
@RueNahcMohr no, it's jittery as shit!
@gloriouscow ok! well, its good to have a resolution beyond the stability!
so, kalman filter?
so, kalman filter?
@RueNahcMohr just average the last 6 frames or so
@gloriouscow oh no, low pass. That hurts at 59hz
wait, if you get partial hits over a few scan lines, you could use the values together.
@RueNahcMohr whatever CGA paint program you're using isn't updating at 60Hz anyway, so its mostly fine.
@gloriouscow bah, not enough people write in assembler }:/
